CSS Order and Background Property

The "float" parameter in CSS allows an element to be pushed to the left or right, allowing other elements to wrap around it. A floated element will move as far to the left or right as it can.

The elements before the floating element will not be affected      Eg: .img { float:right; } If you place several floating elements after each other, they will float next to each other if there is room.

The clear property specifies which sides of an element other floating elements are not allowed.      Eg: .text_line { clear:both; } Reference :   W3c Help Clear Example in Stack Overflow

Function .prototype is a constructor property whose value is the function itself.  Since they are objects they can be passed as objects. When a function is invoked with .(Dot) or [Subscript] then the function becomes a method.  The Function by default gets "arguments" as default argument even if it is not present in function signature however it is not exactly an array object but has "length" property.

When we use Nested Functions "This...
